Distinct variety of geranium named Glacier Crimson

ABSTRACT

A new geranium cultivar is distinguished by its brilliant color, short and compact plant, more basil branching, close internodes, small leaves and short flower stems with the flowers positioned immediately atop the foliage.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Pelargonium hortorum, Bailey known by the varietal name of Glacier Crimson, formerly known as Bruni. The new variety is a seedling resulting from the cross of the seed parent J-line of Adonis and the pollen parent J-line of Adonis.

The new cultivar was discovered in the year 1977 in Dresden, German Democratic Republic; was first asexually reproduced by cuttings in Dresden, German Democratic Republic and has been repeatedly asexually reproduced by cuttings at Oglevee Floral Company in Connellsville, Pa. over a three year period. It has also been trialed and field tested at Northwestern Washington State Experimental Station in Mt. Vernon, Wash. It has been found to retain its distinctive characteristics through successive propagations.

The new cultivar, when grown in a greenhouse in Connellsville, Pa., using natural light and 62° F. night temperature and 70° F. day temperature, has a response time of six weeks from a well rooted cutting to a flowering plant in a four inch (10 cm.) pot.

DESCRIPTION OF THE DRAWING

The accompanying photographic drawing illustrates the new cultivar, the color being as nearly true as possible with color illustrations of this type.

DESCRIPTION OF THE NEW PLANT

The following detailed descriptions set forth the characteristics of the new cultivar. The data which defines these characteristics were collected from asexual reproductions carried out by the Oglevee Floral Company in Connellsville, Pa. The plant history was taken on six week plants, blossomed under natural light in a greenhouse and color readings were taken indoors under 100 foot candles of cool, white fluorescent light. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London.

REPRODUCTIVE ORGANS

Stamens:

Anthers.--Approximately 8 arranged cylindrical and carried at same height as stigma.

Filaments.--Pure white to red at the tips; 0.95 cms. in length.

Pistils:

Number.--1.

Length.--0.95 cms.

Stigma.--5 arms reflex back; reddish in color.

The new cultivar is characterized by its brilliant color and a short and compact plant. There is more basil branching and close internodes and small leaves as compared with the standard bush zonal geraniums produced in the United States. A short flower stem positions the flower immediately atop of the foliage into the plants and renders the plant very resistant to wind and rain damage. The red coloring is accentuated by the purple throat which appears on the upper petals. 

I claim:
 1. A new and distinct variety of geranium plant substantially as herein shown and described.
